Oil Pump Adapter

[Kevin H]

Hi Thor :-)
It's been a while!

On mine it is the pump body that is cracked, but I think Peter's problem is with the adapter plate (see picture).

If originality was not a concern it is easy top buy a replacement (higher performance) pump, plus a remote filter kit for considerably less than £500.

Kevin yes its my adapter plate that is broken where the oil line fitting screws into the cast housing as seen on the left of your photo.

Yes you can buy replacement pumps either standard , high volume or high pressure but your comment on buying a remote oil filter is also correct but you still need the item I have been chasing.

Some of the high pressure or hi volume pumps are longer in the body . There is very little clearance between the pump with adapter attached and the cross member. Approach with care.

To fit any replacement pump you have to either remove the motor or as I did support the motor with a trolley jack and remove the 2 engine mount bolts and with care jack the motor up high enough to enable the oil pump retaining bolts to be removed

Good point Peter about the clearance!

I have a Melling M63HV pump on my car now and I suspect the oil pump cover has been removed and replaced with something like the item shown in the attached image - it's a Milodon Billet Aluminum Oil Pump Cover - 21225. They can be bought from several sources in the US for about US$220.

This would solve the problem. The intake on the right hand side would be capped and the two ports on the left hand side go to the remote filter.

Seem exactly what I was chasing . Is it fitted to your car in place of the bristol adapter? Why my chrysler contact didnt know of it ? How did you get onto this setup ?

Do you have the third inlet blocked off?

Peter,
I don't know exactly what the oil pump cover is on my car - it was sourced by the guy who rebuilt the engine. He was/is an expert on the Chrysler B/RB engines and sourced most parts from the US. I just know it's a Melling M-63HV pump, although that's very similar to a standard pump.

My pump cover has two front facing ports like the Milodon cover, but I don't know if it has another inlet at the rear. The car isn't very accessible at the moment - I will check when I can.

I'm fairly certain that the third port is for use with a dry sump set up.

I have since found a discussion thread on a Mopar forum where they discuss this;

Here are the two relevant posts;

Thread title: Remote oil filter adapter for BB pump

Question:
"I am using the internal oil pickup. I only need to have the fittings on the pump for the remote filter. These pump covers that include both the remote filter fittings, and the external oil pickup lines, can I just plug the pickup line holes?
Will they then work with the internal oil pickup passages (stock/hemi)?
For example, the Milidon-21225"

Answer:
"There shouldn't be any issues if you wanted to plug off the external pickup line and just use your existing internal setup, as long as you use the same pump. Some of the race pumps don't have holes drilled for internal pickup."

However, if Bristol has an original one presumably that's cheaper that buying the Milodon product?

Although the Milodon one is probably less likely to fail than the original one.

That Milodon unit looks really fine.

Peter,
I have had a closer look at what oil pump cover is on my car (it's very hard to see!), but I have taken a picture from the front.

It's not a Milodon. It looks more link the original cast steel pump cover, but it's different to yours, and different to what used to be on my 411 - the lower port is at a different angle. So it just has the pressure relief spring retainer on the rear (no third port). I can't tell whether it is a one-piece pump cover, or two piece .

Kevin just a guess its probably off a jensen intercepter they have one pipe pointing towards the radiator and as I understand the other coming off at an angle.

They are as scarce as hens teeth.
